Arguments
id
An atomic vector.
...
More atomic vectors.

dat <- Phenobarb[1:56,] # First 4 subjects
attach(dat)
is.unsorted(Subject) # TRUE - the original column is NOT sorted
is.unsorted(asID(Subject)) # FALSE - the ID is sorted
all(as.character(Subject) == as.character(asID(Subject))) # TRUE - textually they are the same
cbind(ID=asID(Subject), dat)
